Google Earth recently added a timelapse feature, equal parts mesmerizing, sobering and incredible. Timelapse in Google Earth combines 24 million satellite photos captured between 1984 and 2020. That’s 37 years of deforestation, urban sprawl, shrinking glaciers, tar sands, agriculture, irrigation, mining and coastal erosion in high definition interactive timelapse. Choose a theme, play, pause on a given year, zoom in, scroll about – kudos Google, job well done. Google Earth introduced Timelapse as “longest video in the world”, 20 petabytes ( one petabyte equals a million gigabytes ), my head spins.
On March 19, 2021 Iceland’s Geldingadular volcano woke from a six thousand year slumber. A relatively minor eruption, more curiosity than threat by Icelandic standards despite being 20 kilometers from Reykjavik. Burping Geldingadular isn’t far from the Blue Lagoon, a man-made geothermal spa fed by water from a nearby power plant. Blue Lagoon (geothermal spa) – Wikipedia On March 31st, Wioleta Gorecka ran with a friend’s suggestion to capture the “big three” – volcanic eruption, aurora and the blue lagoon. Her whim took my breath away –
Geminid Borealis by Adrien Mauduit at Night Lights Films takes my breath away. Envious is an understatement. Oh to be perched on a peninsula in Norway witnessing the Geminids through tendrils of ethereal auroras.
SDO, NASA’s Solar Dynamics Observatory marked its 10th anniversary in June 2020. Ten years and 425 high resolution images later, SDO gives us a decade of Sun. Ponder this remarkable video, every second represents one day –
Adrian Mauduit at Night Lights Films launched a mesmerizing timelapse endeavor titled Explore the Night Sky. From Night Lights Films –
“Welcome to this new series of educational videos about the cosmos titled ‘Explore the Night Sky’. They consist of short episodes focusing on one celestial object or phenomenon that can be observed from Earth. They are kid friendly and their purpose is to make people discover the sky at night while encouraging science education and promoting the fight against light pollution. In this episode, we feature the open star cluster ‘Pleiades’, aka Messier 45, M 45 or the ‘Seven Sisters’ through a series of time-lapse sequences taken in various locations around the Earth (Norway, Switzerland, Spain, Chile). A lot of people have seen this small patchy group of star without realizing it contains about 1000 of them! Learn more about it by watching the rest of this mesmerizing film.”
Natural phenomenon needn’t be mysterious. Ponder Aurora Borealis, arguably one of nature’s greatest phenomenon, least mysterious spectacles. Aurora are offspring of space weather, nothing mysterious about that. On May 11, 2020 Earth is expected to cross a fold in the heliospheric current sheet. In less mysterious language – disruption of interplanetary space separating opposing magnetic polarities of Earth and Sun, briefly over riding Earth’s magnetic field, inviting solar energy to temporarily dazzle sky watchers with aurora majesty – consider yourself schooled in solar sector boundary crossing, a space weather basic.
Solar wind is the source of space weather. Just like Earth, the Sun has a magnetic field known as interplanetary magnetic field (IMF). Whipped into spiral rotation, wind driven IMF rotates in one direction dividing into spiral sections pointing to and away from the sun along an ecliptic plane ( direct line between Earth and the Sun). The edge of this swirling mass has a surface separating polarities of planetary and solar magnetism called the heliosphere current sheet.
Earth’s magnetic field points north at the magnetopause (the point of contact between our magnetosphere and the IMF). If the IMF happens to point south at contact the field link causes partial cancellation of Earth’s magnetic field – in other words, opening a temporary door for solar energy to enter our atmosphere. Welcome solar sector boundary crossing – a phenomenon born of high solar wind and coronal mass ejections (CME’s – aka solar flares).

Seeing is believing, pictures speak a thousand words, right? Not so fast – ponder photographic perspective. Swedish photographers Olafur Steinar Gestsson and Philip Davali conducted a little experiment for photo agency Ritzau Scanpix. The premise was simple, capture images of the same subject matter at the same time from two perspectives. One with telephoto, the other a wide angle camera lens.
For weeks my photographer husband has criticized headline images of irreverent social distancing. Not to say it doesn’t exist, far from it. That said, it’s worth pondering how telephoto images are used to sway, reinforce or punctuate public perception. Now I get it.
A compilation of 1,200 images taken over four days by Mars rover Curiosity resulted in this 1.8 billion pixel resolution panoramic postcard from Mars. Struggling to express how remarkable this is, I’m acutely aware of how happy it makes me.
